I have just spent a month in Siriwipa's condo apartment and I couldn't be happier. The description and photos are accurate and Siri is super friendly. I had a late flight into BKK and arrived at the condo at about 1am and Siri still managed to personally greet me on arrival which I thought was wonderful. The place itself was clean, comfortable and cosy. Internet is quick with no drop-outs. A new 7-11 has opened under the condo so all your essentials can be purchased without leaving the complex.
The location is 15-20 minutes walk from Nana BTS and about the same to the Petchaburi MRT and airport link. I will definitely be returning if the condo is available during my next stay.
